GENERAL DESCRIPTION:
TYPICAL APPLICATIONS:
The FPM2750QFN is a packaged pair of
pseudomorphic
High
Electron
Mobility
Transistors (pHEMT) specifically optimised for
balanced configuration systems. The Filtronic
0.25µm process ensures class-leading noise
performance.
The use of a small footprint
plastic package allows for a cost effective total
system implementation.

TEST CONDITIONS
ABSOLUTE MAXIMUM
TAmbient = 22°C unless otherwise noted; exceeding any one of these absolute maximum ratings may
cause permanent damage to the device
RF Input must be further limited if input VSWR > 2.5:1
Total Power Dissipation is defined as: PTOT = PDC + PIN – POUT
where PDC = DC Bias Power, PIN = RF Input Power, POUT = RF Output Power
Total Power Dissipation shall be de-rated above 22°C as follows:
PTOT = (150 – TCASE ) / ΘJC W
where TCASE = Temperature of the thermal pad on the underside of the package
ΘJC increases linearly from 124°C/W at a TCASE of 22°C to 145°C/W at a TCASE of 145°C
Information on the mounting of QFN style packages for optimum thermal performance is available on
request.
BIASING GUIDELINES:
•
•
•
•
Active bias circuits provide good performance stabilization over variations of operating
temperature, but require a larger number of components compared to self-bias or dual-biased.
Such circuits should include provisions to ensure that Gate bias is applied before Drain bias,
otherwise the pHEMT may be induced to self-oscillate. Contact your Sales Representative for
additional information.
Dual-bias circuits are relatively simple to implement, but will require a regulated negative voltage
supply for depletion-mode devices used in the FPM2750QFN
Self-biased circuits employ an RF-bypassed Source resistor to provide the negative Gate-Source
bias voltage, and such circuits provide some temperature stabilization for the device. A nominal
value for circuit development is 4 Ω for a 50% of IDSS operating point.
For standard Class A operation, a 50% of IDSS bias point is recommended. A small amount of
RF gain expansion prior to the onset of compression is normal for this operating point. Class A/B
bias of 25-33% offers an optimised solution for NF and OIP3.
